PreserVision AREDS 2 Formula

PreserVision AREDS 2 by Bausch + Lomb is the gold standard eye supplement for adults over 50 at risk of age-related macular degeneration. It is the only eye vitamin formula directly based on the landmark AREDS2 clinical trial funded by the National Eye Institute, and it remains the supplement most recommended by ophthalmologists in the United States. If your eye doctor has flagged early or intermediate AMD, this is the formula they are almost certainly going to suggest.

What Is PreserVision AREDS 2?

PreserVision AREDS 2 is a targeted nutritional supplement designed to slow the progression of age-related macular degeneration. It exists because of one of the most important studies in eye health history — the Age-Related Eye Disease Study 2 (AREDS2), conducted by the National Eye Institute and published in JAMA Ophthalmology in 2013.

The original AREDS trial in 2001 showed that a specific combination of vitamins and minerals reduced the risk of progressing to advanced AMD by about 25%. AREDS2 refined that formula by replacing beta-carotene with lutein and zeaxanthin, eliminating a lung cancer risk for smokers while maintaining the same protective effect.

Bausch + Lomb manufactures PreserVision as the direct consumer product based on the AREDS2 formula. No other eye supplement can make this claim with the same level of clinical backing. This matters because the supplement industry is full of eye health products that borrow individual ingredients from the AREDS research but use different doses, different combinations, or add unproven extras.

What’s Inside

Each daily serving (2 soft gels) contains:

• Lutein 10mg — A carotenoid that concentrates in the macula and filters harmful blue light. Sourced from marigold flowers. This is the dose used in the AREDS2 trial.
• Zeaxanthin 2mg — Works alongside lutein in the macular pigment. The 5:1 ratio of lutein to zeaxanthin matches the AREDS2 protocol.
• Vitamin C 500mg — An antioxidant that protects retinal cells from oxidative damage. The dose is high but matches the trial.
• Vitamin E 400 IU — Another antioxidant that works synergistically with vitamin C in the retina.
• Zinc 80mg (as zinc oxide) — Zinc is highly concentrated in the retina and plays a role in melanin production, which protects the eye. This is the high-dose protocol from the trial.
• Copper 2mg (as cupric oxide) — Included specifically to prevent copper deficiency, which can occur with long-term high-dose zinc supplementation.

The formula does not contain beta-carotene, omega-3 fatty acids, or any herbal ingredients. Every component and dose directly mirrors the AREDS2 trial protocol.

What the Research Says

The evidence behind PreserVision AREDS 2 is exceptional by supplement standards. The AREDS2 study, published in JAMA Ophthalmology in 2013, enrolled 4,203 participants aged 50-85 across 82 clinical sites. Participants had bilateral intermediate AMD or advanced AMD in one eye.

The study confirmed that the lutein/zeaxanthin formulation was as effective as the original beta-carotene formula in reducing the risk of progression to advanced AMD — approximately 25% risk reduction over five years. Crucially, the lutein/zeaxanthin version eliminated the increased lung cancer risk that beta-carotene posed to smokers and former smokers.

A 10-year follow-up published in JAMA Ophthalmology in 2022 found that participants who took lutein/zeaxanthin instead of beta-carotene had an additional long-term benefit: lower rates of late AMD and a statistically significant reduction in lung cancer risk. This cemented the AREDS2 formula as the preferred version.

No other eye supplement has anywhere close to this level of evidence. Most competing products rely on observational studies or small trials with surrogate endpoints like macular pigment optical density. The AREDS studies measured actual disease progression in thousands of patients over years.

Who Is This Best For?

PreserVision AREDS 2 is the right choice if you:

• Have been diagnosed with intermediate AMD in one or both eyes — this is the primary indication backed by trial data
• Have advanced AMD in one eye and want to protect the other eye
• Have a family history of AMD and your ophthalmologist recommends preventive supplementation
• Are a current or former smoker — the AREDS2 formula is specifically designed to be safe for this group (no beta-carotene)

This may not be the best fit if you:

• Have no signs of AMD — the trial did not study people without existing disease, so the preventive benefit is unproven
• Are looking for general eye health support — Ocuvite 50+ or a lutein-only supplement may be more proportionate
• Have trouble tolerating high-dose zinc — some people experience nausea or stomach cramps at 80mg

How to Take It

Take 2 soft gels daily with a meal. The fat in your food helps your body absorb the lutein, zeaxanthin, and vitamin E — all of which are fat-soluble. Taking them on an empty stomach reduces absorption significantly.

Splitting the dose (one soft gel with breakfast, one with dinner) may reduce stomach discomfort from the zinc if that’s an issue for you.

Watch for nutrient overlap: If you take a multivitamin, check whether it contains vitamin E, zinc, or vitamin C. Stacking PreserVision with a full multivitamin can push you well above tolerable upper limits — especially for zinc (upper limit is 40mg, and PreserVision alone provides 80mg by design). Many doctors recommend choosing one or the other, not both.

Drug interactions: High-dose zinc can interfere with the absorption of certain antibiotics (tetracyclines, quinolones) and penicillamine. Space them at least 2 hours apart. Vitamin E at 400 IU may interact with blood thinners like warfarin — discuss with your doctor.

The Bottom Line

PreserVision AREDS 2 is the most evidence-backed eye supplement available. If you have intermediate AMD or your ophthalmologist has recommended AREDS vitamins, this is the formula that matches the trial protocol exactly. The clinical evidence is Level 1 — a large, randomized, controlled trial — which is rare in the supplement world. For AMD-specific protection, nothing else comes close.

Always consult your doctor before starting any new supplement, especially if you have existing eye conditions or take prescription medications.
